摘要
硫代硫盐法是最有希望取代氰化法的提金方法,氨及铜氨络离子在浸金以及从贵液中回收金的过程中发挥着重要作用。综合评述了硫代硫酸盐浸金及金回收过程中氨、铜氨络离子的作用机理和影响。
Thiosulfate is the most promising system to replace the toxic cyanide for gold leaching.Ammonia and copper ammonia ion play major roles in the process of gold leaching and gold recovery from pregnant solution.The function of ammonia and the copper ammonia complex ion are reviewed in this paper.
